The 295.33 driver is now included in ubuntu. I can't tell if it fixes this issue, but the changelog does specify a couple display-port related fixes.
Please update to 295.33 and re-test if this issue can still be reproduced with that version. ** Changed in: nvidia-graphics-drivers (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/877682 Title: [Latitude E6510 / Thinkpad W510/T510] External Video inoperative with nVidia current To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/877682/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
